Moreno Compressor Station Modernization Project

The Moreno Compressor Station has been operating safely and reliably since the 1950s. The modernization of the nearly 75-year-old infrastructure is required to comply with South Coast Air Quality Management District (South Coast AQMD) air emissions requirements. In June 2021, SoCalGas submitted a Permit to Construct application for the Moreno Compressor Modernization Project. The main purposes of the project are to:
 

• Comply with South Coast AQMD Rules 1100, 1110.2, and 1134 under which South Coast AQMD is sunsetting its RECLAIM (Regional Clean Air Incentives Market) program for nitrogen oxide (NOx) emissions and is transitioning to a command-and-control structure with equipment specific emissions limits. Facilities previously in RECLAIM must comply with updated emissions standards 
• Modernize the Moreno Compressor Station through the replacement of aging natural gas fueled compressors with a combination of new natural gas fueled and electric driven compressors that will achieve significant reductions in NOx emissions
• Enhance reliability by modernizing aging equipment and ancillary systems

The Moreno Compressor Station is critical in providing supply for customers who rely on natural gas for heating, cooking, hot water, and power. In fact, the Moreno Compressor Station contributes to the delivery of over 95% of the natural gas that is consumed in the County of San Diego, including residences, businesses, hospitals, schools, and power plants.
